(a) If the Regional Administrator determines that the ACL for any coral bed will be reached prior to the end of the fishing year, NMFS shall publish a document to that effect in the Federal Register and shall use other means to notify permit holders. Any such notice must indicate the fishery shall be closed, the reason for the closure, the specific bed being closed, and the effective date of the closure.

(b) A closure is also effective for a permit holder upon the permit holder's actual harvest of the applicable quota.
